Welcome to the Dell Community  @Ixicix 

Disconnect the AC adapter.

Remove the battery.

Hold down the power button for 10-15 seconds.

Then connect only the AC adapter and power-on.

EDITED:

1. Power-on the computer.

2. As the computer boots, press the (F12) key as the Dell logo appears.

3. On the boot menu screen, select the Diagnostics option.

The Enhanced Pre-boot System Assessment window is displayed, listing all devices detected in the computer.

The diagnostics starts running the tests on all the detected devices.

4. If you wish to run a diagnostic test on a specific device, press and click Yes to stop the diagnostic test.

5. Select the device from the left pane and click Run Tests.

6. If there are any issues, error codes are displayed.

I went in Bios and slected UEFI toshiba, thats my usb. It showed dell screen and after a black screen.

Everytime i try to boot something, it either shows the windows or dell logo and a black screen appears after that.

Everything passed except for the webcam and the hard drive, sometimes. The hard drive passed too. Problem.still occurs, what do i do? Reinstall windows? Also I cant cant a automatic repair because its just a black screen.

BTW, there are no instructions.

@Ixicix 

Sounds like you need to reinstall W10.

Insert your W10 USB drive.

Power-on and start tapping the (F12) key.

Boot from USB and follow instructions.
